There are a couple /x/ comics about Green Pill. (These might have originated around summer 2014.) They voice acted them and made videos of that. I also include /pol/ Iron Pill comics saved from imgur.
"no one person made it pic related is the earliest form I know. Someone else did fill it in to make greenpill and the others though, and he did it quite nicely with the tinfoil and book cover" - /x/14627281 on the proto green,red,blue pills.
"The original comic that started it all. I was in the thread where it was first posted. Legendary times, legendary times." - said by /pol/55549516
"As autistic as this might sound, iron pill comics got me to quit weed, booze, shitty food, and start lifting. Yesterday I hit a 405 deadlift, and I haven't touched a substance in over a year. I cook all of my own meals sourced from farmers markets, and local butchers." - /pol/55548948
